What is the difference between a disc brake and a stationary float?
Fixed caliper disc brakes have the following disadvantages:(1) more cylinders, so that the brake caliper structure is complex;(2) the oil cylinders are arranged on both sides of the brake disc, and must be connected with the caliper oil passage or the outer oil pipe across the brake disc. This makes the caliper too large to fit in the rim of a modern car;(3) when the heat load is large, the oil tank (especially the outboard cylinder) and the brake fluid in the oil pipe or oil passage across the brake disc are easy to heat and vaporize;(4) if a parking brake is to be used, a mechanically actuated parking brake caliper must be installed.
These shortcomings make the fixed caliper disc brake is difficult to adapt to the requirements of modern cars, so since 70s, gradually gave way to a floating caliper disc brake, because the disadvantages of floating fixed caliper these inevitably do not have one, in addition there are smaller advantages of floating light weight easy to realize electronic etc..
Fixed finger pliers fixed, plates float in general, through the piston on both sides to promote friction plate to clamp the brake disc.
Suspension type generally refers to pliers floating, and the single side piston pushes the friction plate to drive the pliers to slide to clamp the brake disc;
